Couch Gag

A couch gag is a running visual joke in the Opening Sequence of The Simpsons. The couch gag changes from episode to episode, sometimes with the placement of the couch changing. In more recent seasons, the couch gags have tended to be more outlandish and absurd, sometimes showing the Simpson family sitting on the couch in different types of media (claymation, live-action, flipbook animation, etc.).
